ath79: remove redundant setup of wmac for ubnt WA devices

Several Ubiquiti WA devices set up &wmac again in their DTS files,
although this is already done in ar9342_ubnt_wa.dtsi.

Fixes: fa3c2676ab0c ("ath79: Add support for Ubiquiti Nanostation AC")
Fixes: cf5a1abe46fc ("ath79: define 2.4GHz radio for nanostation ac loco")
Fixes: 09804da80a99 ("ath79: define 2.4GHz radio for litebeam ac gen2")
